. fication.

This invention relates to a book mark. The primary object ofthis invention resides inthe provision of a book mark, whereby the utilization of the same will permit any number of pages of a book to be securely retained in a convenient separable condition from those remaining to be read. Another object of this invention resides in the provision of a book mark, adapted to be removably attached to the'cover or back of a book with the marking finger of its securing means utilized to retain the pages thereof in a convenient separable condition from those remaining to be read.

A further object of this invention resides in the provision of a book mark, adapted to be utilized for various sizes of books without necessitating a change in its construction.

A still further object of this invention resides in the provision of a book mark, adapted to be secured to the front or back of a book with its securing means yieldingly engaging opposite edges thereof, in addition to maintaining the same action upon the marking finger.

A still further object of this invention resides in the provision of a book mark,

adapted to be supported by the front or back of a book with its securing hooks engaging the opposite edges thereof and hold ing the marking finger in a stationary position through the medium of an elastic connecting strap.

A still further object of this invention resides in the provision of a book mark adapted to be secured to the front or back of a book with its marking finger constructed of a pliant material.

In the accompanying drawin s, Figure 1 howing this book mark attached thereto and the marking finger thereof engaging a plurality of pages supposed to have been read. Fig. 2 is a view of a book in open position with this book mark in a similar position as shown in Fig. 1. Fig. 3 is a detail perspective view of the marking finger as constructed in connection with one supporting hook thereof. Fig. 4:, is a detail perspective view of a modified form of the supporting hooks of this book mark.

Referring more particularly to the present embodiment of this invention the numeral 5 designates an elastic strap which has its terminals overlapped as at 6 and stitched a suflicient distance from the bending point thereof to provide loops 8 for the reception of two separate strands of pliant wire 9 of different lengths. These strands .of wire may be successfully utilized as originally produced, but as occasion may arise wherein it may be necessary to provide a covering for the same, I reserve the right to attain this end by employing any approved process which will not be detrimental to the initial utility of the same.

After having passed the shorter wire 9 through one of the loops 8 until each protruding end is an equal distance from the adjacent side of the loop, the same is bent at right-angles to that portion thereof which lies within said loop, whereupon a further bending action forms their terminals into hooks 10. The aforesaid hooks when formed as thus described are utilized in engaging the lower edge of a book cover, while the upper edge of the book is engaged by a hook 11 of similar construction and length, but formed at the shorter protruding end of the aforesaid longer strand of wire. This strand of wire is passed through the remaining loop of the aforesaid elastic strap 5, with its major portion bent at right angles to the loop engaging portion thereof to produce a marking finger 12 that is formed of pliant material and adapted to be bent over a plurality of pages in a book after the same have been read.

In Fig. 4: is shown an elastic strap 12 similar in every respect to that hereinbefore mentioned, in the looped ends 13 of which are supported hooks 14 and a marking finger 15 similar to that heretofore described, but have their shanks twisted as at 16 to form strap engaging loops 17 to prevent the strands of wire from slipping through the loops should the tension of said elastic strap be exerted, as by applying the book it can be readily bent over a multiplicity of book pages without disengaging the hook formed thereon from the book cover or back.

In progressing with the reading of a book having this book-mark attached thereto, it is simply necessary to bend the page marking finger over the edges of those pages that have been read when a discontinuance of the reading is desired, whereas in future readings the pages remaining to be read'may be slipped between those formerly read and the marking finger until they become very compact, after which it is necessary to rebend the marking finger over the edges of all pages having been read, and thus leaving those unread to remain loose and to be similarly separated as they are read at a future reading. 7

Having thus described my invention, I claim,

1. A book mark comprising hooks engaging the opposite edges of a book cover, a

pliant page marking finger formed integral with one of said hooks, and means yieldingly connecting said hooks.

2. A book mark, comprising, spaced hooks engaging the lower edge of the cover of a book, a hook engaging the upper edge of the cover of a book, a contractile strap connecting said upper and lower hooks, and a pliant page marking finger formed integral with said upper hook in spaced relation thereto.

3. A book mark comprising a contractile strap, strands of wire having their intermediate portions secured to the opposite ends of said strap, hooks formed at the ends of one strand of wire, a hook formed at one end of the other strand of wire, and a pliant page marking finger formed at the other end of the second mentioned strand of wire.

4. A book mark comprising a contractile strap, strands of wire having their intermediate portions engaged by the opposite ends of said strap, hooks formed at the ends of one strand of wire with their shanks twisted around one another, a hook formed at one end of the other strand of wire, and a pliant page marking finger formed at the opposite end of the second mentioned strand of wire with its shank and that of the second mentioned hook twisted around one another.

In testimony whereof I afiix my signature in the presence of two witnesses.
